This program is a Nagios check the monitors servertech PDU / CDU devices using the Sentry3.mib MIB. It checks the following:

1) Environmental temperature (Auto-detects all sensors)
2) Environmental humidity (Auto-detects all sensors)
3) Input power (Auto-detects all input feeds)

Though Net::SNMP may be installable using package systems such as yum or apt. Both plugins may have to be done by hand like this:

# perl -MCPAN -e 'install Nagios::Plugin'
# perl -MCPAN -e 'install Net::SNMP'
